ONE-HANDED: Vertical sharps drop disposal minimizes excessive handling and reduces the risks associated with horizontal "mail-box" type disposal. Once the self-contained screw cap is secured and locked, leakage of fluids during handling, transport and disposal is virtually eliminated. Containers are available in translucent red and clear. The 1.0, 1.5 and 2.5 gallon sizes can be used freestanding or with metal stands or metal cabinets. The bulk 3.5 and 6.0 gallon containers are designed for freestanding use only.
